Am new to Angular 2. I completed 5 min Quickstart tutorial and moved on to try this ScotchIO example. Am just trying to use the same exact code as is in the example. When i run npm start command after installing node module through npm install am getting follow exception. 

[system]:~/Coding/Angular2/SecondApp$ npm start

And this how my project folder structure looks like :

[system]-ThinkPad-L420:~/Coding/Angular2/SecondApp$ ls -ltr
total 48
-rw-rw-r--   1 admin admin   204 Jul 26 21:40 typings.json

-rw-rw-r--   1 admin admin  2932 Jul 26 23:09 npm-debug.log

Tried few suggestions in StackOverFlow but it was of no help.

As its shown in your project structure, there is no typings folder and you missed it out from your first 5min QuickStart example.

The typings folder could not show up after npm install. If so, please install them manually.

npm run typings install

This should resolve the problem.
